Abstract
A plasma lighting system includes a magnetron configured to generate microwaves, and a bulb filled with a main dose and an additive dose. The main dose and the additive dose generate light under the influence of microwaves and have maximum intensities of respective intrinsic wavelengths at different wavelengths. A motor is configured to rotate the bulb. A controller is connected to the motor. The controller adjusts the Revolutions Per Minute (RPM) of the bulb to thereby adjust a color temperature of light emitted from the bulb.
